GRAND RAPIDS, MI—Alarmed Grand Rapids data-entry clerk Clifford Gornowicz, 33, quickly calculated the age difference between himself and 17-year-old Tonight Show guest Gaby Hoffman while watching the program Monday. "Man... 16 years," Gornowicz said to himself after host Jay Leno disclosed the actress' age. "That means she wasn't even born when The Empire Strikes Back came out. Oh, God." Gornowicz has reportedly not been this distressed since Christina Ricci.
